Here's a link to the actual video:

https://www.youtube.com/watch?v=DDO2EvXyncE

This appears to be flight stabilized and guided via direct command coming from the launcher. It is not an autonomous guided missile.

On the defensive side, see perhaps this phased array radar system with an 20km range:

What a time to be alive.

In fact, I think I now have all I need to start a war with my neighbours.

notlenin•48m ago
you could have started a war with your neighbors using only sticks and stones - indeed, much of human history is people starting wars with their neighbors using weapons that we today would call primitive.

But now you can start a very destructive war with your neighbors. Thanks to modern technology, you don't have to bother beating your neighbor to death with a wooden club, you now can annihilate them, and basically anything in their immediate vicinity, from a comfortable distance :D

Somewhat interesting in that the Pentagon did not want the E-7 (as a replacement to the E-3):

* https://www.twz.com/air/e-2-hawkeye-replaces-usaf-e-3-sentry...

nominally because it wanted to spend the money on more E-2s, which can operate on smaller and rougher airfields, which would be handy in (e.g.) the Pacific where tiny islands don't necessary 'fancy' runways that the E-7 needs.

But they're actually very handy in tracking tiny targets—like drones—so Australia is sending E-7(s) to the Middle East:

Congress rebuffed the Pentagon's attempted to 'completely kill' E-7 acquisitions, and the USAF has now put in an order, and it may be that people now realizing having some number of E-7s may be handy:

In the two test launches shown in the video, the "missile" doesn't fly straight nor does it demonstrate ability to be "guided" by the launcher towards any particular target.

It's also incredibly slow. There are children's rocket kits that fly significantly faster than this.

embedding-shape•1h ago
Yeah, neither article nor the video itself talks about "accuracy" AFAIK, which seems like a kind of important thing in this whole concept, otherwise it's just a "horizontal rocket launcher" which is cool I guess, but not so close to a MANPAD.

The video is also cut in a way so you cannot tell that the launch seems to have been a complete failure? The rocket is vertical at the last frame: https://i.imgur.com/e2Kld6I.png

nine_k•51m ago
I frankly would care little about the speed; it can always be improved with a better propellant. I would care about a cheap ability to guide the rocket. If it's there, it may be consequential for a real (para)military application.

(A quadcopter is perfectly guidable, but it must be slower than a rocket, and costs more than $96.)

giantg2•48m ago
Guidance systems have speed limitations. Just because it works when slow does not mean it will work if you upgrade propellant.
NoSalt•46m ago
Baby steps ... with a few more contributors, this could be turned into, say, a $500.00 missile that works quite effectively.
snowwrestler•5m ago
The engine and the warhead are two of the biggest challenges in making a missile, in large part because anything high performance is also going to be spectacularly dangerous to manufacture.

> Despite the tech-cool factor of the project, Tom's Hardware does not condone making your own weapons system at home.

Not that this matters for the topic, but I don't see why people have started saying "weapons system" instead of "weapon".

Guided missile launchers are weapons systems, because the projectile and the launcher each are a component of a complete system which requires significant technology. This is in contrast to a firearm, which has all of the technology in the gun and not the ammunition (for the most part) or more simply a knife or sword.
robertlagrant•30m ago
I suppose I'd say: well, no, a gun's ammunition does something significant, but also even if that disambiguation were necessary in a particular circumstance, this article is not that.
esseph•15m ago
> This is in contrast to a firearm

This changed long ago. Optic, light, IR illuminator, IR pointer, NVG/thermals. The rifle or carbine is now a component of the weapon system.

SiempreViernes•11m ago
I think ultimately it's a consequence of weapons manufacturers in the US is trying to make their products sound more impressive, and in general military terminology is a huge nonsensical mess.

Just consider that "self propelled gun" and "main battle tank" are very different things despite the first being a quite accurate description of what the latter consists of. Or the distinction between a cruise missile and a one way drone...

tokai•6m ago
Nobody has started saying weapon systems instead of weapon. Its just precise terminology.
cucumber3732842•42m ago
I think with the proliferation and effectiveness of countermeasures passive target acquisition and first shot accuracy with traditional ballistic methods might be a better place to focus but I understand that's very hard to do nonprofessionally as an individual thanks to the rules and laws.

On the other hand, there is a lot to be said for making them blow their $1k active countermeasures on your $500 missiles before sending a real one in to finish the job. Heck, even just forcing your adversary to treat every sky like it's hostile is worth a lot.

Both approaches are clearly worthy of development.

I think this violates ITAR. You aren't allowed put a guidance system on a rocket. And even if you were allowed to do it for your own fun/education, you certainly aren't allowed to provide instructions to foreign entities about how it do it.
mothballed•20m ago
It's life imprisonment just to possess a launcher (not even the rocket) that is intended to launch a rocket/missile that guides towards an aircraft. And the guy has another youtube short where he explicitly says the intended guidance system is cameras that update the location of a missile and then he shows a real drone and also the emblem of an aircraft as intended targets for this guidance system, while also calling it a MANPADS launcher.

That's before you even get to ITAR.

Those of us who have seen people get nailed to the wall for having a almost to scale picture of a machinegun part on a piece of metal, or people convicted of possessing rocket launchers because the ATF put an entirely different gun inside of an deactivated tube and claims it is a rocket launcher because the ATF's own gun could fire inside of it, are watching this with our jaws dropped because we've seen that even bad faith representation of intent that were so much looser than this end in serious convictions.

Hasz•31m ago
Regardless of whether this actually works (I have my doubts, but also understand it might be difficult to get range time on a device like this :)), it exposes a fundamental issue with arms control today.

Small firearms are hundreds of years old. Drones have been commercially available for many years and are easily modifiable into something that is 80% as good as what is currently being fielded in Ukraine.

It is not technically feasible to restrict someone from assembling basic, non-firearm-specific components to build a firearm. In the US, there is an increasing effort at the state level to serialize, restrict, and document individual firearm parts. However, an 80% good barrel can be fabricated at home, a 100% as good receiver can be printed on any recent 3D printer, and the rest of the parts (bolt, trigger assembly, etc) can be designed around easy home fabrication (see FGC-9). There is no practical way to trace, regulate, or stop behavior.

It isn't possible to restrict someone from building a capable drone either. The firmware is opensource, the parts can be ordered from almost any marketplace, and an energetic payload can easily be made by any amateur chemist from chemicals in any hardware or camping store. EW is often touted as a solution, but is frequently beaten by tethered drones. Cheap COTS IMUs are getting good enough to provide surprisingly accurate short-term INS, to say nothing of autonomous systems that need no external input past initial targeting.

I personally think this is a far bigger risk than most countries realize, largely because they are 10-15 years behind the technology. I believe this will force most governments into spending an order of magnitude more to defend their institutions at every level, not just core government security.

At least in the US, these threat vectors will absolutely be used to justify intrusions into civil liberties, but no amount of infringement will be able to even partially mitigate these threats. I think this should start to play out over the next 5-10 years.

idiotsecant•27m ago
I am certainly pro T2A but your argument doesn't hold - laws to regulate arms are not effective only in a binary way - if they reduce the number of arms they are doing what they say on the tin.

Whether we should be trying to regulate arms is another issue.

mothballed•24m ago
Obama and Biden were the best gun salesman the USA has had in awhile. It's not clear they reduce the number of arms, depending on the culture. In USA culture we've seen the number of arms in civilian hands expand even as regulations increase.
Hasz•5m ago
I am not arguing laws need to be binary-effective. You are right, most of the current laws are designed to slowly erode public support for the 2nd amendment by making the barrier to entry so absurdly high that the average person cannot feasibly own firearms.

I am arguing that the new laws being proposed (e.g serializing other firearms components, ammo serialization, assault weapons bans, higher gun-owner standards) have absolutely no bearing on an entirely new source of firearms. Many Dem-controlled states have passed "ghost gun" regulation, but there is no real enforcement mechanism and it's mostly an additional charge to tack on after an actual crime has been committed.

You can see states like CA trying to go after 3D printers, but I suspect this will fail. There is no software out there that can realistically determine whether a part is a firearm component, other than dumb hashes of known parts. 3DP is a general tool, it is like trying to ban milling machines, files, or basic handtools.

quamserena•11m ago
These discussions always focus around enforcement and never on alignment. The moat for this stuff historically has never been strict enforcement; it has been that the people who have the know-how on how to do it have nothing to gain by doing it, since they are well-educated and benefit from the current socioeconomic order (they have no motive to change it; rather, they want to climb it).

This is shifting. First, economic stratification is getting worse, and as economic mobility declines people start looking for alternatives. (See all of Gen Z cheering for Luigi Mangione). Second, AI will enable people who are less educated to build these kinds of weapons.

For example, you can use a Kalman filter to greatly improve the data you get from an IMU and GPS via sensor fusion. Before, this required a specialist skillset; now you can get a "good enough" implementation by prompting Claude.

I really wish the debate around this stuff wasn't framed in terms of preventative enforcement because it naturally leads towards more enforcement (when your only tool is a hammer...). The root of the issue is that the government does not trust its citizenry to follow the law without Big Brother watching. That in and of itself is a symptom of a larger grave political crisis in America: the decay of the state's political legitimacy.

When everyone started working on 3D-printed guns, I was sitting here thinking that if it comes to actual revolution, one is going to need anti-tank/anti-air a whole lot more than (relatively easy to acquire) small arms... Nice to see movement on this front
ericmay•2m ago
In the American context, hopefully it never comes to an actual revolution, because life for everyone will be much, much worse with little prospect of anything being better afterward. We should do what we can to avoid one, especially because while it's fun to fantasize about your side being the one to start a revolution, there's no reason to think that the other side won't also think the same way and maybe they'll beat your side and make your life really, really awful.

Secondarily, there's a lot to say about anti-tank and anti-air power in the context of a "revolution". Most of it is pure fantasy including the idea that 3D printed missiles are going to start striking US strike aircraft at 40k feet in the equally absurd fantasy that those aircraft are going to just be bombing American cities and towns and countrysides. It's really just pure Internet-driven fantasy to think that these scenarios are plausible or the least bit desirable in any fashion.

the__alchemist•10m ago
I will be a negative yancy, and regurgitate things from the previous thread in combination with my pattern-matching brain and experience with making UAS firmware/hardware etc.

Cool project, but this is the 1% of the work that's required to get an initial platform in place. It cannot intercept an airborne target, and it will take the rest of the 99% of the work on testing, refining guidance/propulsion/sensors etc, finding and fixing errors, finding and fixing incorrect assumptions that will lead to re-building various subsystems etc.

Another way of phrasing it is that this is a cargo cult MANPADS.
